memos.

To all whom it may concern Be it known that I, CARROLL Honors, a citizenof the United States, residing at Radnor, in the county of Delaware andState. of Pennsylvania, have invented cer tain new and usefulImprovements in Stonage Batteries, of which the following is aspecification.

Storage batteries are usually mounted in so-called hard rubber jarsplaced in wooden boxes, and it not infrequently happens that when thebatteriesare new the jars break causing inconvenience out of allproportion to the relative value ofthe jar.

It is the principal object of the present invention to prevent suchbreakage and its consequent inconvenience.

The contiguous faces of the jars and boxes are not perfectly true andflat and hence are not in contact throughout their extent. In

consequence of this the box wall imperfectly supports the jar wall andthe latter, being brittle and lacking proper support, breaks under theweight of the contents of the ar. By my invention ll secure initiallyperfect contact and therefore eflicient support between the contiguousfaces of the jar and box walls so that the latter contact with andefliciently support the former and hence the jars do not crack butremain in service In describing how I accomplish this result referencewill be made to the accompanying drawings in which Figure 1, is asectional View of a part of a jar and its box. Fig. 2, is a similar viewshowing liquid in the jar, and Fig. 3, is a side view with parts brokenaway of the finished battery.

Referring to Fig. 1, 1, is the wall of a jar, and 2, is the wall of thebox or container. There is shown, more or less diagrammatically, at 3,the condition that arises by reason of the fact that in practice perfectcontact does not exist throughout between the adjacent faces of the jarand the box walls due to the necessities of manufacture and the natureof the materials. If a battery were mounted in the jar with theconditions as above described existing, the jar wall would not besupported at the part 3, and, being of hard Specification of LettersPatent.

' rubber or hard rubber material as it is sometimes called and thereforebrittle, more especially when cold or cool, the jar wall will break forlack of sufficient support or sufficient continuity of support.According to the present invention the jar is put into its box andfilled with hot water or other appropriate hot liquid, as indicated inFig. 2 at 4. The result of this is that the jar wall is softened by the'heat of the water and, induced while soft by the weight of the water toyield sufficiently to come into perfect contact throughout its extentwith the wall of the box, so that by this treatment the space shown at3, in Fig. 2, would disappear and the jar wall will assumethe po sitiorshown in Fig. 1, in which it is in close contact with the box wall andsupported thereby throughout its extent. After the liquid 4, hasproduced the results above described, it is removed and the platestruc-' ture 5, and electrolyte 6, are put into the therefore brittle,will not breakbecause it is supported throughout its entire surface bythe box wall with which it is in continuous contact.

What I claim is:

1. The process of fitting hard rubber jars to their boxes which consistsin assembling the hard rubber jars and boxes in nested relation with thejars full of warm liquid which softens the hard rubber jar walls andforces them, while soft, into intimate contact with all points of thebox walls which thereafter support them, substantially as described.
